Bandwidth is a term used to describe the amount of data that can be transmitted over a network connection in a given amount of time. It is usually measured in bits per second (bps), and determines the speed at which data can be transferred between devices. Bandwidth is a key factor in the performance of a network, and is often a limiting factor in the quality and speed of audio and video streaming, online gaming, and other bandwidth-intensive applications. In general, the more bandwidth a connection has, the faster and more responsive it will be. Bandwidth can be affected by a number of factors, including the type and speed of the connection, the distance between the devices, and the amount of traffic on the network.
